Question

liquid A has a boiling point of 353 K and liquid B has a boiling point of384 K.Both are miscible with each other.They are seperated by "fractional distillation".Justifythe reason for using fractional distillation method

Answer 1

Because fractional distillation is done for two substances having different boiling point.
The liquid having lower boiling point will boil and evaporate before the second liquid in the mixture and hence the two liquids get separated.
